I love this guy. He walls everything except for steel types. Toxic and Protect to stall everything except for steel types. Rest to regain health and Encore to lock a pokemon into a move for my sweepers and to stop baton pass teams.

Togekiss, Dunsparce and Jirachi can make better use of para-flinch because of Serene Grace. Sigilyph can annoy the opponent even more with this:
-Cosmic Power
-Stored Power
-Psycho Shift
-Roost
Nature: Timid
EVs: 252 HP/200 Def/56 Spe
Item: Flame Orb
Ability: Magic Guard

Excadrill needs max Speed so it can outspeed as much as it can in Sandstorm.
